摘　　要：为进一步研究用等位移理论估计高层建筑结构非弹性地震反应,选用五个钢筋混凝土高层结构实例,输入二十条不同场地条件的地震波,采用结构弹性和非弹性地震时程反应分析方法,研究了结构弹性和非弹性最大顶点位移以及最大层间位移角之间的关系。提出可以直接用弹性最大顶点位移估计非弹性最大顶点位移。对于非弹性层间位移角反应,在中、弱非线性阶段宜可直接用弹性反应结果估计,而在强非线性阶段则需进行一定修正。In this article, five actual high rise buildings and twenty earthquake records are selected to further study the inelastic seismic responses of tall buildings. The relationship between the elastic and inelastic earthquake responses of the tall buildmgs is studied by both methods of the elastic and inelastic seismic time history. It is feasible to evaluate directly inelastic top displacement by the elastic top displacement. And the inelastic story drift ratio can be estimated by the elastic seismic response in small and medium nonlinear phases of the tall buildings, but the estimation must be modified in large nonlinear phase.
